Sounds like the InstallMac (aka Genieo) adware. CleanMyMac definitely will not fix this. It may remove some, or perhaps even all, of the visible symptoms, but you can bet you still have components of Genieo installed somewhere. See:

CleanMyMac definitely should be avoided. Macs do not need the "cleaning" that it offers, and the uninstall feature it has is not at all reliable. In addition, the folks who make it seem to think it's okay to have it installed alongside adware, piggybacking in an installer that you were tricked into thinking you needed. This doesn't happen as often with CleanMyMac as it does with even worse programs, like MacKeeper, but it does happen.
